Cristobal Alert: Due to the impending approach of Cristobal, Southeastern employees scheduled to work on campus Monday should plan to work remotely instead. Those employees previously identified as essential should report to work as directed by their supervisors. Please continue to check this site for any updates.

I am generally interested in the behavior, conservation, and evolutionary ecology
of amphibians and reptiles. I am currently focused on two main areas:

First, is a long-term (2003-present) wetlands snake assemblage study in the Lake Pontchartrain
Basin, which produces a massive amount of data on body size, assemblage structure,
habitat association, seasonal activity, and road mortality. Here, my interests are
in species body size scaling, functional patch size of habitats, the effects of flooding,
the effect of roads on mortality, and other general aspects of ecology.

Second, is the evolution of vision in snakes. What are the accommodation mechanisms,
and how are they distributed phylogenetically? More specifically, how have terrestrial
animals that independently evolved eyes in one medium (e.g., air, on land) adapted
to the change in refractive index experienced when foraging in another medium (e.g.,
underwater)?
